Moonshot example documentation is not updated

this example from the documentation is not working, and throwing an error strategies must implement get_signals

also, in the CLI running command, this param is an unrecognized argument: --pdf

ok, so the problem was the version of moonshot.
I was using v1.1.1 while documentation was for v1.2.0

just a suggestion - write the version that the documentation is written for (especially when api/functions break)
also, you should probably indicate version issues in the exceptions themselves.

Documentation is now versioned:
